Hellas is an ancient impact structure and is the deepest and broadest enclosed basin on Mars. It measures about 2,300 kilometers across and the floor of the basin, Hellas Planitia, contains the lowest elevations on Mars. The Hellas region can … Continue reading
THEMIS Image of the Day, February 13, 2017. Today’s false color image shows plains in the northern part of Hellas Planitia. The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to … Continue reading
THEMIS Image of the Day, January 27, 2017. Today’s VIS image, made soon after local sunrise, shows a small portion of Reull Vallis. Reull Vallis is one of the major channels entering eastern Hellas Planitia. More THEMIS Images of the … Continue reading
In this context image is an old degraded crater that has undergone a complex history of burial and erosion. The image shows a surface with at least two types of exposed bedrock, one that is light-toned and one that is … Continue reading
Channels in crater northeast of Hellas Planitia. Beautiful Mars series.
3-kilometer crater and bedrock exposures north of Hellas Planitia. Beautiful Mars series.
Hellas Planitia floor. Beautiful Mars series.
We’re not sure if this channel-inside-a-channel was carved by flowing water or lava. Flowing water erodes channels, and flowing lava both erodes and melts surrounding rock to form channels. It’s not clear whether a huge surge of water or lava … Continue reading
I keep a silent vigil. A crater to the north of Hellas Planitia with possible phyllosilicates in the ejecta. Beautiful Mars series.
THEMIS Image of the Day, June 30, 2015. This unnamed channel is draining from the highlands of Promethei Terra to lowlands of the Hellas Basin. More THEMIS Images of the Day by geological topic.
